ELECTRIC LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 483,204, datedSeptember 27, 1892.

Application filed April 1, 1891. Serial No. 387,201- (No model.)

To aZZ whom it may concern:

Be it known that I, NORMAN C. BASSETT, a citizen of the United States,residing at Lynn, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in ElectricLocomotives, of which the following is a specification.

My invention relates to electric locomotives; and it consists in devicesby means of which the motor is supported so that its armature may beconcentric with an axle of the locomotive.

Referring to the accompanying drawings, Figure 1 is a vertical sectionon aplane transverse to the axle. Fig. 2 is a horizontal section throughthe axle. Figs. 3 and 4 are respectively end and side elevations of themotor; and Figs. 5 and 6 are longitudinal and transverse sections of awheel and axle of the 10- comotive, showing means for connecting the'wheel with the armature-shaft.

Referring to the drawings, A is the armature of an electric motorconcentric with the axle A and mounted on a hollow shaft S, throughwhich the said axle passes.

F is a field-magnet surrounding the armature and having a singlemagnetizing-coil S This field-magnet is provided with journalboxes B,forming bearings for the armatureshaft, so as to secure alignmentbetween the armature and field-magnet.

The motor thus described is supported free of the axle by means ofconnections to the frame of the locomotive, as follows:

B represents longitudinal beams forming a part of the motor framework.These beams are supported on transverse beams 13 with intermediatesprings R R 13 is a transverse bar connecting the two beams B From thebeams B the main weight of the motor is supported by means of links L,extending from said beam-s, respectively, to pivotal points L in linewith the center of gravity of the motor, as nearly as maybe. Asupplementary support is afforded by means of rods 0, which support thefree end of the motor through springs S from the transverse bar 13.

The hollow shaft of the armature is connected with the wheels of thelocomotive in order to properly drive them by means of the followingconnections: The hub of the wheel is provided with four radial arms orflanges R Surrounding these is a drum C, made in two parts and fast onthe hollow shaft S. This drum has an interior series of radial arms orflanges R, corresponding to the arms or flanges B A series of triangularsprings or cushions R is interposed between the radial arms of the wheeland the drum, respectively, and is held in place by the inclosing parts.

By the arrangement thus described I produce a locomotive in which thearmature is directly on the axle, but yet out of contact therewith, andin which the armature drives the Wheels directly with intermediatespringcushions.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in an electric locomotive, of a motor having itsarmature concentrio with an axle of the locomotive and having afioldanagnet with a single coil embracing the armature, a hollow shaftfor the armature, through which passes the axle, a yielding connectionbetween the said shaft and the wheel, and a yielding support for themotor from the frame of the locomotive.

2. The combination, with an electric locomotive, of a motor and meansfor suspending it from the frame of the locomotive, comprising linksextending to the center of gravity of the motor.

3. The combination, in an electric locomotive, of a motor suspended fromthe frame of the locomotive by links extending to the center of gravityof the motor and a supplementary spring connection between the motor andthe frame.

4-. The combination, in an electric locomotive, of a motor having itsarmature concentric with the axle, a field-magnet having bearings tosecure proper alignment between it and the armature, a yieldingconnection between the said armature and a wheel of the vehicle, andmeans for supporting the motor, consisting of links extending from theframe of the locomotive to the center of gravity of the motor, and aspring connection between the motor and frame.

5. In an electric locomotive, the combination, with a motor-armaturehaving a hollow shaft concentric With the axle, of a wheel having radialarms, a drum made in two parts clamped on the hollow shaft and providedWith radial ribs, and yielding cushions between the arms and ribs,substantially as set forth to In witness whereof I have hereunto set myhand this 30th day of March, 1891.
